A new study says crises like the narrowly averted BART strike are likely to continue unless we change the way we fund public transportation.

The study called Stranded at the Station says 90 percent of public transit systems across the country are in severe financial difficulty.

The transportation Equity Network and Transportation for America commissioned the study. They say the slump in the economy has led to an increased demand for public transportation at a time when tax subsidies that keep it affordable are drying up.
